INTERNAL-COMBUSTION ENGINE.

Specication of Letters Patent.

Application led February 9, 1916. Serial No. 77,257.

' tion engines and has for its primary object to provide a cylinder head particularly designed to replace the removable cylinder heads of internal combustion engines in which the inlet and exhaust valves are arranged laterally of the cylinders in housings provided for that purpose whereby the engine is converted into the more modern and efficient type of engine known as the valve in-the-head type.

Another object is the provision of means operable by the original cam shaft of the engine for actuating the valves arranged in the improved cylinder head.

lVith these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, .it being understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or` sacrificing any of the,advan Figure 1 represents a longitudinal sectional view, partly in side elevation', through the improved engine, Fig. `2 represents. a fragments] vertical sectional view on the line 2 2 of Fig. 1 Fig. 3 represents a bottom plan view of' the improved cylinder head, the valves being removed, Fig. 4 represents a detail sectional view through one of the rocker arms, and Fig. 5 represents aV l detail sectional view on the line 5-5 of y Fig. 4.

erally the cylinder block including a plurality of integral individual cylinders 11 which are supported upon 'the crank case 12. The cam shaft 13 is operatively supported in the crank case 12 laterally of the cylinders 11 and is provided with-the usual push rod operating cams 14 engaging the lower sections 15 of the valve operating push rods. The upper extremities of the cylinders 11 are formed with integral lateral hollow projections 16 in which are arranged a plurality of vertically dis osed partitions 17 dividing the interior` o the housing or projection 16 into inlet and exhaust chambers -18 and 19, respectively, the two inlet chambers 18 of two adjacent cylinders being intercommunicating and the two exhaust chambers 19 being separated 70 from the inlet chambers 18 by the partitionsl 17. The inlet chambers 18 are connected with one terminal of an inlet manifold 20 whereby gaseous fuel is. conducted to the chambers 18 from where it-is drawn into the cylinders 11 of the engine during the suction stroke of the istons 21. The exhaust chamber 19 of eac cylinder is connected with a branch 22 of the exhaust manifold 23 whereby the exhaust products of combustion discharged during the scavenging stroke of the pistons 21 are conducted from the engine.

In internal combustion engine cylinders of the Ltype the valves are ordinarily arranged laterally of`the bore of the cylinders 1'1 and are adapted to enga e in seats 24 formed in the upperw'all of t e housing 16. The stems of the valves project downwardly through guides 25 formed integral with the lower portion of the housing 16 and engage the upper ends of the push rods 15 whereby eration yof the engine.

In applying myv'improved cylinder head to l use, I remove the val-ves which ordinarily eh:- gage in the-seats 2li-'and also the head which is bolted or otherwise secured over the upper open ends of 'the housings 16 and cylinders 11 and replace the old cylinder head by the improved head designated venerally` by the numeral 26. The improve head ,is preferably cast in one piece andisconstructedso as to tightly fit over the upper ends of the cylnders 11 and housing 116. A suitable type they are mechanically opened during the opwalls n lof metal bound wat 917 is fitted between Y the head 26 and t cylinder block 10.

Over each cylinder 11 the head ,26 is formed with a cavity 28- constituting a combastion chamber and the top, side und end of they head are formed with water chambera 29 whereby the head is effectively cooled during operation of the engine. The

\ up er wall oi' each combustion chamber 28 is ornied with inlet and exhaust ports 30 and 31, respectively which communicate with the horizontal portions of -Lshaped inlet arid exhaust chambers 32 and 33 respectively. The lower extremities of the vertically disposed portions of the inlet and exhaust chambere 32 and 33 communicate with the inlet ind xllixaust clmmbjers l'118 anlili Il?, respective y, o' t e bemin 6 t roug t e original valve seats 2 4 of ghe e 'ne AThe edges of the inlet and exhaust rts 3D and .31 are beveled to provide seats or inlet and exhaust valves 34 and 35 respectively, which are provided with upwardly extending st ems 86 and 37, respectively, engaged with the inner extremities of a pair of rocker' arms 38 ivotally supported upon a shaft 8 9`and con- IEiued between pairs of adjustable collars 40. The valve stems 36 and 37 for each cylinof the engine are slidably mounted in and engaged by, apertured enlargements 40* formed integral with the top of the head 26 of the valves 34 Vand 35 and also rethined in clonedv position by springs 41 colledubout the Stems 36 and 37 and engaging the enlargements 40 at their lower cada after (he caps or ti 42 fitted upon the uplper cada thereof. he central portion of t e rocker arma 88 are formed with lubricating a rtlm 43 and the uptpcr portiourofthe aft 89 ia cut awa as in icated at 44 to receive a Yad of absorbent material 45 adapted to re tain' a q'uantit traction to e actively lubricate t rock r arms to operate with the engine. The sha 39 is supported in uprigli'ts 46 attached to the top of the head 26 and the shaft; rocher arma and parts aseoci ted therewith are ineloeed in e casin 47 removably attached to 26. The ends of the rocker arms 38 opposite those engaged by the valve stems 36 and 37 are engag over and operated by the upper sections 48 of theycam operated ushrods. The upper push rod sections f8 extend downwardly throuh apertures formed in the upper portion of t e head 26, throu h tubular guides arranged in4 the L-sliaped c iumheiu 32 und 33, the cham` bers 18 and 19 in the rhousing 16 und the guides 25. 'The tubular guides are engaged at their lower ends with the ides 25 and are curel at their upper enz. s in apertures formed inthe head 26 y ring nuts. Intermediate each pair of inlet and exhaust cha`mbers 32 and 33, the upper portion of the comof lahricator by ca illary at'- .stema and push bustion chamber 28 is formed with u spark 6b plu ieceivin opening 50.,.

I* rom the oregoing description taken in connection with the accom iinying drawings', it is clearly evident that l)have provided a novel andeflicicnt type of cylinder heads for interim! combustin engines having the vulves arranged within the combustion chamber of the engine und operated from above the cylinder head which may be ap` plied to existing types of L-type internal combustion engine cylinders.
